WSClean version 2.10 ==================== Released 2020-07-15 WSClean 2.10 depends on `IDG version 0.7 `_ or newer. Summary of changes: WSClean can now run on multiple nodes using MPI. Several new methods for calculating a-terms were added: position-delta screens, better kernel windowing, gridding with the VLA beam and joint deconvolution of multibeam/PAF systems (which was demonstrated using Apertif). This is the last version that is released via SourceForge. Future development will move to GitLab: https://gitlab.com/aroffringa/wsclean. Major & visible changes: * Support for distributed computing using MPI * Support for "position shift screens" (dldm-screens) during a-correction gridding * Support for joint deconvolution of PAF / multi-beam observations * More windowing options for a-correction kernels, defaults now to "raisen Hann" * The VLA beam has been implemented * Support imaging of multiple fields * Add parameter ``-multiscale-max-scales`` * Restore source component models using ``-restore-list`` Bug fixes & other changes: * Properly weigh channels when averaging with user-set deconvolution channels. * WSClean could iterate infinitely when first multiscale scale is not 0 * GCC 10 fixes * Improved error reporting * Fix inversion timing
